• MongoDB: A NoSQL database that allows for flexible data modeling, ideal for handling various survey question types and responses.
• Docker: For containerization, enabling easy deployment and management of application instances.

3. Interesting Implementation Details

Dynamic Survey Logic

• Conditional Logic: The system allows for dynamic question display based on previous answers. For example, if a user selects “Yes” to a question, a follow-up question can be displayed, while selecting “No” can skip to the next relevant question.

  Example of conditional logic implementation:

  if (answer === 'Yes') {
      displayFollowUpQuestion();
  } else {
      skipToNextQuestion();
  }

Customizable Themes

• Custom colors, backgrounds, and logos.
• A user-friendly interface for theme selection and customization.

Data Analysis Capabilities

• Cross-tabulation analysis to identify trends and correlations between different survey questions.
• Data export options for further analysis in external tools.

4. Technical Challenges Overcome

Handling Large Volumes of Data

• Pagination: When displaying survey results, pagination is used to load data in chunks, reducing the load on the server and improving response times.

  Example of pagination implementation:

  const pageSize = 10;
  const currentPage = 1;
  const paginatedResults = allResults.slice((currentPage - 1) * pageSize, currentPage * pageSize);

Security Measures

• Data Encryption: Ensuring that all data transmitted between the client and server is encrypted using HTTPS.
• Access Control: Implementing role-based access control to restrict access to sensitive data based on user roles.

Integration with Third-Party Tools
